How many liters will 10.0 grams of hydrogen occupy at stp​

Chemistry
1 answer:
Dmitrij [34]3 years ago
4 0

Answer:

38.36 L.

Explanation:

  • We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of H₂ in atm (P = 1.0 atm, STP conditions).

V is the volume of H₂ in L (V = ??? L).

n is the no. of moles of H₂ in mol (n = mass/molar mass = (10.0 g)/(2.0 g/mol) = 5.0 mol).

R is the general gas constant (R = 0.0821 L.atm/mol.K),

T is the temperature of H₂ in K (T = 0.0°C + 273 = 273.0 K, STP conditions).

<em>∴ V = nRT/P</em> = (5.0 mol)(0.0821 L.atm/mol.K)(273.0 K)/(1.0 atm) = <em>38.36 L.</em>

In the formation of a solution how does the solvent differ from the solute
dlinn [17]
Solute is a substance that dissolves in a solvent in order to form a solution. Solutes can be in liquid, gaseous or solid phase. Normally, in a solution, solutes are in a lesser amount than the solvents. When a solution has the maximum amount of solutes it can dissolve, then the solution is said to be saturated.

IRISSAK [1]

Answer: A loss of the ion concentration gradient that drives this process.

Explanation:Ouabain known as g-strophanthin, is a cardiac glycoside that can be medically used to treat hypotension.It acts by nhibiting the sodium - potassium (Na/K-ATPase) by causing a loss of the ion concentration gradient that drives it's process. Originally, it was a toxic plant that was used as an arrow poison in eastern Africa for hunting and warfare. Recently, Ouabain is synthesized by animals and secreted from the adrenal cortex to regulate body osmosis.

What is the value for the kinetic energyfor a n = 2 Bohr orbit electron in Joules?
Vladimir [108]

Answer:

<u>K.E. = 5.4362 × 10⁻¹⁹ J</u>

Explanation:

The expression for Bohr velocity is:

v=\frac{Ze^2}{2 \epsilon_0\times n\times h}

Applying values for hydrogen atom,  

Z = 1

Mass of the electron (m_e) is 9.1093×10⁻³¹ kg

Charge of electron (e) is 1.60217662 × 10⁻¹⁹ C

\epsilon_0 = 8.854×10⁻¹² C² N⁻¹ m⁻²

h is Plank's constant having value = 6.626×10⁻³⁴ m² kg / s

We get that:

v=\frac {2.185\times 10^6}{n}\ m/s

Given, n = 2

So,

v=\frac {2.185\times 10^6}{2}\ m/s

v=1.0925\times 10^6\ m/s

Kinetic energy is:

K.E.=\frac {1}{2}\times mv^2

So,

K.E.=\frac {1}{2}\times 9.1093\times 10^{-31}\times ({1.0925\times 10^6})^2

<u>K.E. = 5.4362 × 10⁻¹⁹ J</u>
